Fluid Filter Functional Component Securing Contour
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid filters face the challenge of preventing accidental release of the mechanical connection device between the functional component and the filter housing, which can lead to improper filtration and safety issues.
Innovation Solution
The implementation of a securing contour on the component connection element of the functional component, which interacts with a joining element connected to the filter housing, creates a form-fit connection that secures against accidental release, eliminating the need for additional securing components and mounting steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical connection device is used to connect the functional component to the filter housing, then the functional component can be easily assembled and disassembled, but the connection may be accidentally released during operation
Solution Approach 1:
The securing contour is pre-formed on the component connection element, and the joining element is pre-formed on the housing connection element. When the components are assembled together, the securing contour automatically engages with the joining element to prevent accidental release, eliminating the need for separate securing actions or components.
Solution Approach 2:
The mechanical connection device self-secures through the interaction between the securing contour and joining element. Once assembled, the form-fit connection automatically prevents accidental release without requiring additional securing components or actions, making the system self-sufficient for maintaining connection stability.
2Reliability
If additional securing components are added to prevent accidental release, then connection stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The securing function is merged into the existing mechanical connection device by forming the securing contour on the component connection element and the joining element on the housing connection element. This integration eliminates the need for separate securing components, reducing overall device complexity while maintaining connection stability.
Solution Approach 2:
The component connection element and housing connection element serve multiple functions: they provide the primary mechanical connection for assembly/disassembly ease, and simultaneously provide accidental release prevention through their integrated securing contour and joining element features.
3Reliability
If a securing mechanism is integrated into the mechanical connection device, then accidental release is prevented, but the assembly process becomes more complex
Solution Approach 1:
The securing contour and joining element are pre-formed as integral features of the component connection element and housing connection element respectively. This preliminary formation allows the securing mechanism to be built-in during the primary manufacturing process, avoiding the need for separate assembly steps or additional manufacturing operations.
